GRADING-MACHINE FOR BUILDING AND REPAIRING ROADS- Specification ofLetters Patent.

Patented May 28, 1907.

Application filed February 15,1907. Serial No- 357,526-

To all whom, it may concern: y

Be it known that I, WALTER ATLAs J owes, a citizen of the United States,residing at Coolidge, in the county of Thomas and State of Georgia, haveinvented a new and useful Grading-Machine for Building and RepairingRoads, of which thefollowing is a specification.

This invention relates to grading machines for use in building andrepairing roads.

The object of the invention is to provide a novel arrangement of diskplows for loosening the soil.

A still further object is to provide powerful and efficient meansadapted to be readily operated manually. for directing the disks towardor away from the surface of the ground so as to make the cuts of variousde sired depths.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a side elevation of the machine; Fig. 2 isa plan view thereof; Fig. 3 is a section on line x-x, Fig. 2; and Fig. 4is a section on line y-y, Fig. 2.

Referring to the figures by characters of reference, 1 is a frame ofsuitable proportions mounted on supporting wheels 2 in the usual or anypreferred manner and pivotally connected to the sides of the frameadjacent the rear end thereof are depending arms 3 con-,

nected to opposite portions of a diagonally arranged scraper blade 4.One of the arms 3 extends upward to form a lever 5 carrying a springpressed dog 6 adapted to engage a toothed sector 7 so as to lock thescraper in any desired position. A supporting bar 8 is pivotallyconnected to one side of the frame and has a hooked end 9 adapted toextend under one of the arms 3 so as to hold the blade 4 out of contactwith the ground when the same is not in use. Although the scraper hasbeen shown and described it is to be understood that the sameconstitutes no part of the present invention and that otherconstructions than that shown may be employed if desired.

Guide strips 10 are secured longitudinally upon the sides of the frame 1and slidably mounted between these strips and the sides of the frame areguide plates 11 formed at the ends of a cross strip 12 extending underthe frame. These guide plates have inwardly extending flanges 13' attheir upper edges which bear upon the sides of the frame 1. The crossstrip 12 has a rack bar 14 secured transversely thereon adjacent one endand this rack is engaged by a sector 15 formed at the lower end of alever 16 which is fulcrumed upon one side of the frame 1. A toothedsector 17 is disposed adjacent the lever and is adapted to be engaged bya spring pressed dog 18 so as to hold the lever in any position to whichit may be adjusted. Hangers 19 are rigidly connected to the cross strip12 and extend downward therefrom preferably at an incline. The lowerends of these hangers are slotted as shown at 20 and are provided withretaining strips 21 which are bolted or otherwise fastened thereto andserve to close the lower ends of the slots.

Arms 22 are pivoted to the sides of the frame 1 and extend downwardlytherefrom and journaled within the lower ends of these arms is a shaft23 which is normally diagonally disposed in relation to the frame 1.Arranged on this shaft is a plurality of disks 24 each of which has asleeve 25 rotatably mounted on the shaft. These sleeves serve to holdthe disks spaced apart desired distances. Shaft 23 and certain of thesleeves thereon are seated within the slots 20 and are designed to worklongitudinally of the slots when the arms 22 are swung upon theirfulcrums. 7

It is of course understood that when the parts are disposed as shown inFig. 3 it becomes impossible for the arms 22 and the shaft thereon toswing because they will be held against movement by the hangers 19.These hangers can only be shifted with the cross strip 12 and said stripis normally locked against movement by means of the dog 18 and thesector 17. When it is desired to swing the disks 24 downward so as toincrease the depth of the cut into the soil the lever 16 is swung towardthe rear of the machine and as a result the mutilated gear 15 will forcethe rack bar 14 forward. This movement of the rack bar will cause acorresponding movement of the cross strip 12 and the hangers 19 willpress against the rotatable element therein and cause the arms 22 toswing forward and downward thereby carrying the disks 24 therewith. Ofcourse the arms 22 are incapable of moving independently of the hangers19 and when the hangers l thereto, a shaft ournaled within said ch areonce locked against movement by means of the sector 17 and dog 18 thedisks 24 become fixed in relation to the frame 1. Should it be desiredto raise the disks from the ground the movement of the lever 16 isreversed and this will cause the hangers 19 to pull downward onj'shaft23 and as aresult the arms 22 will be swung upwardly and rearwardly. Itwill be seen that by providing lever 16, rack bar 14 and hangers 19 apowerful leverage is obtained upon the arms 22 and therefore the disks24 can be readily forced into the soil and easily raised therefrom. Ofcourse as the disks are arranged diagonally in relation to the frame 1it is apparent that as they move forward they will out furrows withinthe ground and the scraping blade 4 which follows the disks will gatherthe loosened soil and deflect it laterally from the machine.

Importance is attached to the particular means devised for adjusting thedisk plows because of the powerful leverage which is obtained and alsobecause of the compact and durable nature of said mechanism.

What is claimed is:

1. A machine of the character described comprising a portable frame, aplurality of earth engaging devices, pivoted supports therefor, andslidable means for actuating the supports.

2. The combination with a portable frame; of a plurality of earthengaging devices, pivoted supports therefor and suspended from theframe, and slidable means for actuating the supports to raise or lowerthe earth en gaging devices.

3. The combination with a portable frame; of a shaft, earth engagingdevices connected thereto, shaft supports pivotally connected to theframe, and slidable means engaging the shaft to swing the supports.

4. The combination with a portable frame;

of supporting elements pivotally connected to the frame, a shaftconnecting the lower ends of said elements, earth engaging devicesmounted thereon, and means slidably mounted upon the frame and looselyengaging the shaft for swinging said shaft and its supporting elements.5.
